HARNESS-SUPPORTING AND HEDDLE-IiYE-SELECTING DEVICE FOR MACHINES FORDRAWING IN WARP- THREADS.

. SPECIFICATION forming part of Letters Patent No. 500,965, dated July4, 1893.

Application tiled April 26, 1892. Serial No. 430.787. (N0 model.)

To all whom it may concern: 7

Be it known that I, LEWIS P. SHERMAN, a citizen of the United States,and aresident of Biddeford, York county, Maine, have invented certainImprovements in Harness-Supportin g and Heddle-Eye-Selecting Devices forMachines for D rawin g in Warp-Threads, of which the following is aspecification.

My invention relates to certain improvements in machines for drawing inwarp threads, the present application being confined to certain improvedconstructions of the mechanism for hanging and supporting the harness,and in the mechanism for separating the heddle eyes and holding saidheddle eyes in proper position for the action of the threading needle,as more fully set forth hereinafter.

The general construction of the machine, so far as relates to itsoperating mechanism; the mechanism for operating the needle and thethread selecting mechanism, may be similar to that shown in LettersPatent granted to me on the 28th day of December, 1886, No. 355,221, andto which reference is had for details of operating mechanism omitted inthis case for the sake of clearness, or if desired, the needle operatingmechanism and the thread selecting mechanism may be of the characterillustrated in applications for Letters Patent filed of even dateherewith, Serial Nos. 430,786 and 430,788, or of any ordinary orpreferred construction.

The objective point in all heddle eye selecting mechanisms is theseparation of each successive eye in-the heddle from its fellows, andthe clamping or holding of such eye in proper position during thepassage of the needle to the warp frame at the rear of the machine, asillustrated in the above mentioned Letters Patent, and during the returnof such needle with the warp thread hooked; after which the threadedheddle eye is pushed out of the path of the needle and the nextsucceeding eye takes its place in readiness to be threaded; thethreading, of course, being alternately on the successive eyes ofdilferent heddles where two or more of such heddles are to be threadedfor use in the loom.

In the accompanying drawings:-Figure 1,

is an elevation of sufficient of the reciprocating carriage B, of themachine described in the patent above referred to, to illustrate thedevice for operating the selecting hooks and 5, 6, 7 and 8, are diagramsillustrating the different positions assumed by the heddle eye selectinghooks and the clamping jaws. Fig. 9, is a perspective view illustratingthe mechanism for operating the heddle; and Fig. 10, is a sectional viewof adetail.

The carriage B is supported and guided upon a stationary frame and isslowly moved transversely across the machine by mechanismof any suitablecharacter, such for instance as that illustrated in the hereinabovementioned Letters Patent, and the shaft K (see Fig. l) on which aremounted the operating cams, is revolved through themedium of bevel gears70, is from a vertical shaft J having on its upper end a bevel gearj,the

teeth of which mesh withthe teeth ofa bevelgear on a suitably supportedpower driven shaft (not shown).

The mechanisms for selecting and holding the heddle eyes are supportedin suitable bearings upon standards 1, 2 and 3 secured to the carriage Band the heddles to be operated upon, (two in the present machine,) arehung, one between the standards 1 and 2, and the other between thestandards2 and 3. Before describing the selecting mechanism, however,reference will be had to Fig. 9, which illustrates the manner in whichthe heddles tical portions of the posts 4, 4. On the upper ends of thebolts 5--5 are guiding boxes 77, in which is placed a bar 8, theopposite ends of which are rectangular in cross section while thecentral portion of the bar is triangular in cross section and hasinclined sides which form at the bottom of the bar a comparatively sharpedge, as shown in Fig. 9. Running parallel with the bar 8 and at a pointsome distance below said bar, is a second bar or rod 9 havingitsopposite ends bent upward and secured to the bar 8, the bar 9 being atsome distance below the bar 8 and the two bars being inserted betweenthe opposite rows of the heddle cords as shown, the bar 9 separatingsuch cords to a slight extent and aiding the action of the selectinghooks described hereinafter; the tapered edge of the bar 8, however, issuch that the cords may swing freely and be operated upon withoutfriction on the sides of said bar. The upper bar 10 of the heddle framerests upon the bar 8 and the lower bar 11 of the heddle frame isweighted by a cross bar 12 which is attached to the lower heddle bar 11by hooks 13 extending from boxes 14 on said bar 12, the boxes 14 beingadjustable longitudinally on said bar in order to adjust the hooks 13 toaccommodate different lengths of heddle frames.

To adjust the heddle frame transversely after it has been hung in themachine in this manner, I provide at one side of the machine a handledoperating lever 15 fulcrumed at 16 on one of the standards 4, andprovided with a link 17, the opposite end of which carriesa pin 18adapted to enter one or other of a number of recesses 19 formed in thetop of the bar 8 so that said bar 8 and the heddle frame thereon may beadjusted to any position. hen the machine is not in operation theweighted bar 12 is hung upon depending hooks 20 secured to the standards4.

The standards 1, 2 and 3 are secured to the reciprocating carriage B andupon said standards are fulcrumed the Various levers which carry andoperate the mechanism for selecting and holding the heddle eyes, andmotion is imparted to such levers through the medium of cams 21 and 22operating upon the holding jaws, and pins 23 carried by the cams 22which operate upon the levers carrying the selecting hooks. The shaft K,in the present case, is in the form of a sleeve, and through this sleeveprojects a rod 24 carrying at its outer end a separating disk orspreading ring 25 and connected at its inner end to an operating lever26 fulcrumed at 27 to the frame, this construction of the shaft beingused in connection with the thread selecting mechanism described in myapplication for Letters Patent filed even date herewith, Serial No.430,788, the various movements of the thread selecting mechanism beingeifected through a cam 28 mounted upon the shaft K and operating uponthe shaft 29 projecting through the standard 30 carrying a portion ofthe thread selecting mechanism; the spreading ring 25 acting to vary thecontour of the cam 28 in. order to effect dilferent movements of theshaft 29 for the purpose of threading each eye of the heddle with one ormore threads in the body or at the selvage edge of the fabric to bemade.

To act upon the two heddles and to so select an eye alternately in eachheddle, four selecting hooks are used numbered respectively 31, 32, 33and 34, the hooks 31 and 32 acting upon opposite rows of the heddlecords of one heddle and the hooks 33 and 34 acting upon the oppositerows of the other heddle, it being understood that the bars 8 and 9 ofthe heddle supporting mechanism. pass between the opposite cords ofwhich each heddle is formed and separate such cords into two distinctrows on which the hooks operate.

The construction of heddle is such that the upper heddle cords aredoubled and the opposite ends of such a double cord are secured tosuccessive eyes in the heddle, this feature of heddle construction beingclearly set forth in Letters Patent No. 255,038, dated March 14, 1882.

The construction of each of the hooks 31, 32, 33 and 34 is precisely thesame, and the description of one of said hooks Will apply equally wellto each of the others, the only difference being that alternate hooksare reversed to form pairs and the mechanisms for effecting themovements of the hooks are correspondingly altered on the hooks of eachpair, as will be readily understood on reference to the drawings.

Referring now to Figs. 1, 2 and 4, the hook 33 is secured to a spindle35 mounted in the top of the lever 36 and also secured to such spindleat a point below the hook are two arms 37 and 38 one or other of whichis always in contact with a guiding plate 39 secured to the base plate40 carried by the post 2. The guiding plate 39 has a face runningparallel with the slot 41 in the base plate 40 and near one end has arecess 42 and a shoulder The lever 36 is fulcru med at 37 to a pin onthe rectangular base of the post 2 and its lower end is adapted to beengaged by a pin 23 projecting from the cam 22 so that on each rotationof the cam 22 the pin 23 will move such lever, its upper end travelingin the slot 41 and the arms 37 and 38 engaging with the faces of theguiding plate 39; the recess 42 and the shoulder 43 on the plate 39causing an oscillating movement of the hook and its spindle 35 at thetop of the lever 36. The return movement of thelever is effected throughthe medium of a spring 42 secured on one end to the standard 2 andacting upon a pin 43 carried by the lever 36. The swinging movement ofthe hook is effected by the contact of the arms 37 and 38 with the facesof the guide plate 39, as will be more readily seen on reference toFigs. 5, 6, 7 and 8; thus in Fig. 5, the arm 37 is in engagement withthe recess 42 and the hook 33 is at the limit of its forward movement,the lever 36 being has progressed so far as to cause the projection ofthe end of the hook into the path of one row y of the eyes of the heddleY and in Fig. 8, the lever has been moved to its fullest extent and hasreached the opposite end of the slot 41; the hook has been projected toa point just half way between the two rows of the heddle Y and has drawnback all of the heddle eyes to the rear; the arm 37 being in engagementwith the guiding face of the plate 39 and preventing the further outwardmovement of the hook. In following the return movementas a pin 23 movesfarther around the spring 42 returns the lever from the position shownin Fig. 8 to the position shown in Fig. 5, and the arms 37 and 38 beingagain engaged by the guiding plate 39, the recess 42 and shoulder 43effect the oscillation of the hook and move it to the position shown inFigs. 2 and 5. The mechanism for operating each of the remaining hooks31, 32 and 34 is precisely the same; the hook 32 being carried on alever 44 fulcrumed at 45 on the opposite side of the standard 2 and itsarms 37 and 38 being acted upon by the opposite side of the guidingplate 39 in the same manner as are the guiding arms of the hook 33. Thehooks 31 and 34 are mounted respectively upon levers 46 and 47 fulcrumedto the standards 1 and 3 respectively, and being operated upon bysimilar pins 23 carried by the cams 22, the operation of the operatingdevice of each hook is precisely the same, the difference in time oftheir movement being due to the positions of the operating pins 23 onthe cams 22 and the various movements of the hooks being so timed as tooperate properly upon the heddle cords to release the heddle cordcarrying eye which is to be threaded by the needle and to hold back allof the remaining cords untilthis operation has been completed.

43 represent studs projecting from the rectangular base of the standards1 and 2 and pivoted to each of said studs, independently of each other,are two levers 49 and 50, the levers 49 carrying at their upperends theinner clamping jaws 51 and the levers 50 carrying at their upper endsthe outer clamping jaws 52. The lower ends of these levers are providedwith pins or antifriction rollers which engage peripheral cam grooves inthe cams 21 and 22 mounted upon the shaft K and the movement of the camshaft being such that the clamping jaws will be moved to a number ofpositions as illustrated in the diagrams Figs. 5 to 8. Each of thelevers 49 is adapted to a slot 53 in the base plate 40 and its clampingjaw 51 is swiveled thereto so that while the jaw will be given areciprocrating lever 15.

eating motion by the oscillation of the lever it will be free to turn onsuch lever as a pivot. The outer end of the jaw is on a linesubstantially parallel with the main body of the jaw, but somewhatnearer to the opposite clamping jaw 52 and the two portions of the jawareconnected by an inclined portion 54 which rests against the innerplate 55 of the needle guard and when the jaw is thrown back to itsgreatest extent, as will be seen in the diagrams, the inclined face 54in bearing against the portion 55, of the needle guard, causes theretraction of the jaw until it passes entirely in the rear of the needleI guard. From the upper portion of the clamping plate of the jaw 51extends a pin 56 which aidsin holding the heddle eye in position duringthe passage of the needle andprevents the eye from being drawn forwardwhile the thread is being drawn through the eye toward the front of themachine. The needle guards are stationary and comprise an inner shieldplate 55 secured to each of the base plates 40 and being extended beyondthe line of the hooks 31, 32, 33 and 34, as shown in Fig. 4, and theouter portion of the guide is formed by the plate 57 secured to theplate 55 and between the two is a filling piece 58 so that the needle isguided during its passage through the machine and travels in the grooveor guide ways thus formed by the parts 57 and 58. The jaw 52 is swiveledon the head 59 at the upper end of the lever 50; secured to the head 59is a spring 59 Its free end bears against the flattened portion of theswiveled jaw 52 so that said jaw will be kept in proper position when inoperation. The jaw 52 has extending from its clamping face a projectingrib 60 the outer end of which has a projection 61 and the two projectingportions being adapted to be successively brought into contact with theouter guiding face 57 of the needle guard so as to withdraw the jaw fromthe path of the heddle eyes. The end of the projecting portion 60 is ata short distance from the pin 56 carried by the jaw 51 and aids to holdthe heddle eye being threaded in its. proper position. This actionmoreover is aided by guiding pieces 62 secured to the base plates 40 andprojecting into the path of the heddle eyes so that the cords and eyeswill be guided in the proper position within the clamping jaws as shown.

In operation, the heddles to be threaded are first hung on the bar 8,the bar 9 passing through such heddles in such manner as to separate theheddle cords into two distinct.

rows. The bar8 is then placed in position in the guiding box 7 and theweight bar 12 is hung to the lower heddle bar as shown in Fig. 9. Theheddle can then be adjusted in proper position vertically by means ofthe bolts 5 andtransversely by means of the op- Where two or moreheddles are to be threaded the device controlling the I go selection andholding of the heddle eyes are i operated in such manner that an eye inthe first heddle is threaded first, the eyes of the other two heddlesbeing held out of the path of the needle. At the next reciprocation ofthe needle the first eye of the second heddle is threaded and all of theeyes of the first and third or other heddles are held out of positionand so on, the mechanism being exactly the same for each heddle and thetiming of the movements being adjusted to suit a greater or less numberof heddles.

In Figs. 5, 6, 7 and S, I have represented the different positions whichthe parts assume in selecting and threading the heddle eyes, w 00representing respectively the opposite rows of eyes of a heddle X, and yy representing respectively the opposite rows of eyes of a heddle Y.When the parts are in the positions illustrated in Fig. 5, the selectinghooks 31, 32, 33 and 34 are all out of operative position, and one ofthe eyes a: of the heddle X is clamped in position between the jaws 51and 52 and the needle Z is being drawn toward the front of the machinewith the warp thread z, and all of the eyes of the heddle Y are held outof the path of the needle, the eye y of the heddle Y having beenthreaded previously, and preceding this eye in regular order, the eye orand the eye y of the heddlesX and Yhave been threaded and released asshown. In Fig. 6, the selecting hooks 31 and 32 and the clamping jaw 51operating on the heddle X remain in the same position, while theclamping jaw 52 is being withdrawn in the direction of the arrow torelease the eye mwhich has just been threaded; and in Fig. 7, the eye isshown as released and in Fig. 8, is represented as beingpushed forwardby the curved surface on the rear of the jaw 52, as it moves in thedirection of the arrow Fig. 8, to take its former position and all ofthe eyes of the heddle X are held out of position by the jaw 51 in orderthat the needle may next operate upon the eye y of the heddle Y.

The operation of selecting the eye y will be understood on reference tothe diagrams; thus in Fig. 6, the jaw 51 operating on the heddle Y isdrawn back out of the way of the eye y and the eye gradually moves downover the projecting guide 62 until it assumes the position shown in Fig.8, the selecting hook 33 in Fig. 6, is starting on itsrearward movementand in Fig. 7 it has been projected into the path of the eyes y for asufficient distance to hold such eyes back and withdraw them as shown inFig.8. WVhen the hook has reached thelimit of its rearward movement andwhile the hook delays at this point the clamping jaw 51 which has beendrawn all the way back as shown in Fig. 8, is returned to the positionshown in Fig. 5 and the eyey' is held between the jaws 51 and 52 duringthe passage of the needle.
